You can now glue the two side areas and stick them to the pan. I used two clamps clamped to the padding material to keep the padding away from the pan while the glue dried - tie a string to each clamps and pull it sung while the glue gets tacky. Once the first piece of padding is glued you can trim the edge with a pair of scissors - try and hold the scissors vertical so that you trim the material smoothly at the inside edge of the trough where the welt goes. Now you can cut ad glue the second layer of foam in the same manner and trim it the same way as shown in pictures #6, 7, 8 and 9. Note the clamps in the pictures are just sitting there to give the viewer and better idea of how the padding conforms to the seat pan shape.
As mentioned it is possible to apply one piece of padding 1" thick rather than making the padding in two layers of 11/2" if you wish - the last four pictures show the results of the padding being applied in one piece 1" thick.
